    cgraph: Do not warn about caller count mismatches of removed functions
    
    To verify other changes in the patch series, I have been searching for
    "Invalid sum of caller counts" string in symtab dump but found that
    there are false warnings about functions which have their body removed
    because they are now unreachable.  Those are of course invalid and so
    this patches avoids checking such cgraph_nodes.
    
    gcc/ChangeLog:
    
    2021-08-20  Martin Jambor  <mjambor@suse.cz>
    
            * cgraph.c (cgraph_node::dump): Do not check caller count sums if
            the body has been removed.  Remove trailing whitespace.
